Suspensions
INSERT THE BEARINGS. DO NOT HIT THE BALLS AND/OR
THE INTERNAL RING. MAKE SURE THE FOLLOWING
COMPONENTS ARE FITTED PERFECTLY IN:
THE LEFT BEARING «4" ON THE HUB;
THE SPACER «5" ON THE LEFT BEARING
«4";
THE RIGHT BEARING «2" ON THE SPACER
«5";
Front wheel hub overhaul
BEARINGS
Manually rotate the internal ring «1" which must
turn smoothly, without obstacles and/or noise.
There must be no axial clearance. The bearings
presenting these problems must be replaced.
CAUTION
CHECK THAT ALL THE PARTS ARE IN GOOD CONDI-
TIONS, SPECIALLY THE ONES BELOW.
GASKETS
Check that the gaskets are in good conditions; replace them if they show signs of damage or excessive
wear.
WHEEL PIN
Using a dial gauge, check the wheel pin «2" ec-
centricity. Replace the pin «2" if the eccentricity
exceeds the limit value.
Characteristic
Maximum eccentricity:
0.25 mm
RIM
Using a dial gauge, check that the radial eccen-
tricity «A" and the axial eccentricity «B" of the rim
«3" do not exceed the limit value.
An excessive eccentricity is usually caused by
worn or damaged bearings.
Replace the rim «3" if, after the bearings are re-
placed, the value is not within the specified limit.
Characteristic
Maximum radial and axial eccentricity:
2 mm
SUSP - 190
